Abstract
A communications network comprising components configured to implement a method comprising analyzing a path between a first end point and a second end point, and identifying a partial fault along the path is disclosed. Also disclosed is a method for communicating information within a network, the method comprising: defining a path traversing a plurality of nodes, receiving a fault report from an intermediate node, determining whether the fault report affects the path, and responsive to the determination that the fault report affects the path, transmitting the fault report to an upstream or downstream node in the path.
